Maybe. When I took my Barred Plymouth Rocks home, I made a quarantine pen for them out of plastic fencing. One of them laid an egg the next day in the pen!Ohh question. When the new coop is done and we move the chickens into it- they are going to stress and stop laying aren't they? If they do, does this sort of thing generally last days, weeks or months?
They are going on 2 years old and have rarely stopped laying ever! Even through molting.
To be more serious, the most they will stop will be 2 weeks.
This is what I would do. Move them in at night and keep them locked up in the new pen for three nights. Of course make sure you have fake eggs(golf balls) in the nest boxes for them. Also, if it is dark install a light.
I hope it all goes well!
